Clinical features of Ludwig’s angina: There is marked difficulty in swallowing (odynophagia) with varying degrees of trismus. When infection is localised to the sublingual space, structures in the floor of the mouth are swollen, and the tongue seems to be pushed up and back. When the infection spreads to the submaxillary space, submental and submandibular regions become swollen and tender, imparting a woody-hard feel.

PERITONSILLAR ABSCESS/QUINSY - It is a collection of pus in the peritonsillar space which lies between the capsule of the tonsil and the superior constrictor muscle.</p>\n<p><strong>Random:</strong></p><p>Explanation for incorrect options:- Option: A. Peritonsillar abscess is a collection of pus in the peritonsillar space. So option A is correct. Option: B. Marked pain on swallowing that is odynophagia is seen in quinsy. It is so marked that the patient cannot even swallow his own saliva. So option B is also correct. Option: D. Speech of the patient becomes thick and muffled also called a hot potato voice. So option D is also correct.</p>\n<p><strong>Extraedge:</strong></p><p>TREATMENT Hospitalization. Intravenous fluids to combat dehydration. Suitable antibiotics in large i.v. doses to cover both aerobic and anaerobic organisms. Analgesics like paracetamol are given for the relief of pain and to lower the temperature. Sometimes, stronger analgesics like pethidine may be required. Aspirin is avoided because of the danger of bleeding. Oral hygiene should be maintained by hydrogen perox-ide or saline mouthwashes.</p>\n<p>@dams_new_robot</p>", "bot": "@dams_new_robot", "video": ""}, {"text": "You see a lot of cases of neck space infection in the ENT ward.

Profuse, recurrent and spontaneous epistaxis is the most common presentation.</p>\n<p>@dams_new_robot</p>", "bot": "@dams_new_robot", "video": ""}, {"text": "Inverted papilloma is characterized by all except", "options": [{"label": "A", "text": "Also called Schneiderian papilloma", "correct": false}, {"label": "B", "text": "Seen more often in females", "correct": true}, {"label": "C", "text": "Presents with epistaxis and nasal obstruction", "correct": false}, {"label": "D", "text": "Originates from the lateral wall of the nose", "correct": false}], "correct_answer": "B.

A most common site of origin is a lateral wall of the nose in the middle meatus; less commonly it arises from the maxillary, frontal or sphenoid sinus. It is so named because hyperplastic papillomatous tissue grows into the stroma rather than in an exophytic manner. Human papillomavirus is thought to be responsible for its aetiology. Clinically, men are affected more than women in the age group of 40–70. It is almost always unilateral and presents with nasal obstruction, nasal discharge and epistaxis.</p>\n<p><strong>Random:</strong></p><p>Explanation for incorrect options: - Option A. Inverted papilloma also called Schneiderian papilloma is a true statement. Option C. Inverted papilloma presents with epistaxis and nasal obstruction is also a true statement. Option D. Inverted papilloma arises in the Lateral nasal wall in the middle meatus rarely on the septum.</p>\n<p><strong>Extraedge:</strong></p><p>Computed tomography (CT) and magnetic resonance imaging (MRI) shows the location and extent of the lesion. MRI also helps to differentiate associated secretions in the sinus from the actual tumour mass. A biopsy is essential for diagnosis. Treatment. Medial maxillectomy is the treatment of choice. It can be performed by lateral rhinotomy or sublabial degloving approach.</p>\n<p>@dams_new_robot</p>", "bot": "@dams_new_robot", "video": ""}]; if (!Array.isArray(questions) || questions.length === 0) { throw new Error("Questions data is empty or invalid"); } debugLog(`Successfully parsed ${questions.length} questions`); } catch (e) { console.error("Failed to parse questions_json:", e); document.getElementById('error-message').innerHTML = "Error loading quiz data.

Uses OAEs are used as a screening test for hearing in neonates and to test hearing in uncooperative or mentally challenged individuals after sedation. Sedation does not interfere with OAEs. They help to distinguish cochlear from retrocochlear hearing loss. OAEs are absent in cochlear lesions, e.g. ototoxic sensorineural hearing loss. They detect ototoxic effects earlier than pure tone audiometry. OAEs are also helpful in diagnosing retrocochlear pathology, especially auditory neuropathy.

It is used to stent the larynx and trachea after reconstruction for areas of malacia and stenosis. It is a soft stent and can be left in place for periods over 12 months. Its main advantage is that the patient can speak. It is prone to crusting, and to counteract this, it is best to plug the side lumen as much as possible and intermittently perform proper suctioning to prevent blockage. It is not used in children under two years of age as the small size of the stent required has too narrow an internal diameter and can easily become blocked.</p>\n<p><strong>Random:</strong></p><p>Explanation for incorrect options:- Option A.

Option D. Vocal polyp is unilateral, arising from the same position as a vocal nodule. It is soft, smooth and often pedunculated. It may flop up and down the glottis during respiration or phonation.

The patient loses the taste and flavors of the food with a loss of appetite. He is also disadvantaged, unaware of environmental dangers, such as smoke, toxic gases, etc. In such cases, a simple maneuver called polite yawning can be taught, whereby some air passes through the nose . This Manoeuvre consists of lowering the jaw along with its attached muscles of the floor of the mouth and tongue with closed lips. This creates negative pressure in the oral cavity and oropharynx. The patient has to perform the technique several times to induce an inflow of air through the nose. A nasal airflow-inducing maneuver (NAIM) rapidly increases oral cavity volume when the lips are closed airtight. The potential vacuum, prompted by the expansion of the oral cavity, must be filled, resulting in airflow through the nasal cavity. Repeating this maneuver rapidly creates a pumping effect, and sufficient airflow through the nose is established to enable smell.</p>\n<p>@dams_new_robot</p>", "bot": "@dams_new_robot", "video": ""}, {"text": "A 45-year-old male who is a chronic smoker presented with complaints of throat pain, difficulty swallowing, and hoarseness.

Impaired mobility indicates deeper invasion into intrinsic laryngeal muscles or para glottic space and, thus, poor response to radiation . Partnering para glottic or subglottic space is also associated with an undetected attack of laryngeal cartilages and hence poor survival results . With radiation, the cure rate of T2 lesions with normal cord mobility is 86%, which drops to 63% if cord mobility is impaired.</p>\n<p><strong>Random:</strong></p><p>Explanation for incorrect options:- Option: B. Normal cord mobility suggests that surface growth is limited. The vocal cord exhibits a reciprocating respiratory motion, abducting in inspiration and returning to the intermediate position in expiration. Option:C.

It is based on the principle of injecting a photosensitising agent, which is taken up preferentially by the tumour cells and then exposing the site to a specific wavelength of the laser. The laser activates the photosensitising agent, which destroys cancer cells but spares the normal tissues. Photodynamic therapy has also been used for recurrences after surgery, radiation or chemotherapy. Photosensitising agents used intravenously include haematoporphyrin derivative (for head and neck cancers) and photosan-3 (for endobronchial tumours). A topical sensitiser, delta-aminolevulinic acid, has been used for skin cancers (basal cell carcinoma and Bowen disease). An argon-tunable dye laser with a wavelength of 630 nm is often used in photodynamic therapy. It also has the advantage of delivery through flexible fibres. Also, lasers with different wavelengths can be produced by changing the dye. Patients receiving photodynamic therapy should avoid exposure to sunlight and use sun-protective clothing to avoid photosensitive skin reactions, which may continue for several weeks.</p>\n<p>@dams_new_robot</p>", "bot": "@dams_new_robot", "video": ""}, {"text": "Use of lasers in surgery has revolutionised medicine.

The child has an elongated face with a dull expression, open mouth, prominent and crowded upper teeth and hitched-up upper lip.

Adenoids are subject to physiological enlargement in childhood. Certain children tend to generalise lymphoid hyperplasia in which adenoids also take part. Recurrent rhinitis attacks, sinusitis or chronic tonsillitis, may cause chronic adenoid infection and hyperplasia. Allergy of the upper respiratory tract may also contribute to the enlargement of adenoids. Option C. Nasal obstruction is the commonest symptom. This leads to mouth breathing. Nasal obstruction also interferes with feeding or suckling in a child. As respiration and feeding cannot occur simultaneously, a child with adenoid enlargement fails to thrive. Option D. Otitis media with effusion. Adenoids form an important cause of otitis media with effusion in children. Adenoids' waxing and waning size cause intermittent eustachian tube obstruction with fluctuating hearing loss.

Epstein–Barr (EBV) virus is closely associated with nasopharyngeal cancer. Specific viral markers are being developed to screen people in high-incidence areas. EB virus has two important antigens: viral capsid antigen (VCA) and early antigen (EA).

The m ucociliary mechanism is compromised in this case, due to immotile cilia.</p>\n<p><strong>Highyeild:</strong></p><p>Mucociliary mechanism A mucous blanket consists of a superficial mucus layer and a deeper serous layer, floating on the top of cilia, constantly beating to carry it like a “conveyer belt” towards the nasopharynx. It moves at a speed of 5–10 mm/min and the complete sheet of mucus is cleared into the pharynx every 10–20 min. The inspired bacteria, viruses, and dust particles are entrapped on the viscous mucous blanket and then carried to the nasopharynx to be swallowed. cilia beat 10–20 times per second at room temperature. They have a rapid “effective stroke” and a slow “recovery stroke.” In the former, the extended cilia reach the mucus layer.

Histologically, there are areas of mucin-producing and squamous cells, hence the name. The greater the epidermoid element, the more malignant the behaviour of the tumour. The tumours have been further classified as low-grade and high-grade. Low-grade tumours have a good prognosis (90% five years survival rate), and high-grade tumours are more aggressive and have a poor prognosis (30% five years survival rate). Low-grade tumours are more common in children. The behaviour of mucoepidermoid tumours of minor Salivary glands is more aggressive and akin to adenoid cystic carcinoma, but in the major salivary glands, they behave like pleomorphic adenoma. Low-grade parotid tumours are treated by superficial or total parotidectomy, depending on the tumour's location. The facial nerve is preserved. High-grade tumours being more aggressive, are treated by total parotidectomy. The facial nerve may be sacrificed if invaded by the tumour.

A 2 cm long horizontal incision is made in the superomedial aspect of the orbit below the eyebrow . Floor of the frontal sinus is exposed and a hole drilled with a burr. Pus is taken for culture and sensitivity, and a plastic tube inserted and fixed. Sinus can now be irrigated with normal saline two or three times daily until the frontonasal duct becomes patent. This can be determined by adding a few drops of methylene blue to the irrigating fluid and its exit seen through the nose. Drainage tube is removed when the frontonasal duct becomes patent.</p>\n<p><strong>Random:</strong></p><p>Explanation for incorrect Option:s:- Option: A. Antral lavage. Most cases of acute maxillary sinusitis respond to medical treatment. Lavage is rarely necessary. It is done only when medical treatment has failed and that too only under cover of antibiotics. Option: B. Dacryocystorhinostomy (DCR) surgery is a procedure that aims to eliminate fluid and mucus retention within the lacrimal sac, and to increase tear drainage for relief of epiphora (water running down the face). Option: D. Maxillary antrostomy is a surgical procedure to enlarge the opening (ostium) of the maxillary sinus.</p>\n<p>@dams_new_robot</p>", "bot": "@dams_new_robot", "video": ""}]; if (!Array.isArray(questions) || questions.length === 0) { throw new Error("Questions data is empty or invalid"); } debugLog(`Successfully parsed ${questions.length} questions`); } catch (e) { console.error("Failed to parse questions_json:", e); document.getElementById('error-message').innerHTML = "Error loading quiz data.

It may present as a cyst, papule-pearly nodule, or an ulcer with rolled edges.</p>\n<p><strong>Random:</strong></p><p>Explanation for incorrect options:- Option: A. Squamous cell carcinoma is the second most common malignancy, equally affecting both sexes in 40 to 60 It occurs as an infiltrating nodule or an ulcer with rolled-out edges 20% of nodal metastasis is seen. Melanoma is the least common variety and presents as a superficial spreading or nodular invasive type. Option: B. Melanoma is the least common variety. Clinically, it is a superficially spreading type (slow-growing) or nodular invasive type. Treatment is surgical excision.</p>\n<p><strong>Extraedge:</strong></p><p>It is very slow growing and remains confined to the skin for a long time.

If response is seen with increased quantities of water between 5 and 40, labyrinth is considered hypoactive. No response to 40 ml of watering indicates a dead labyrinth. Option C. Electronystagmography is a method of detecting and recording nystagmus, which is spontaneous or induced by caloric, positional, rotational or optokinetic stimulus. The test depends on the presence of corneoretinal potentials, which are recorded by placing electrodes at suitable places around the eyes. The test is also helpful to detect nystagmus, which is not seen with the naked eye. It also permits to keep a permanent record of nystagmus. Option D . In the Optokinetic test, the patient is asked to follow a series of vertical stripes on a drum, moving first from right to left and then from left to right. Usually, it produces nystagmus with a slow components in the direction of moving stripes and a fast components in the opposite direction.</p>\n<p>@dams_new_robot</p>", "bot": "@dams_new_robot", "video": ""}, {"text": "ENT doctor has done a a fistula test for a patient's doubtful case of post-stapedectomy fistula.

A positive fistula also implies that the labyrinth is still functioning.</p>\n<p><strong>Random:</strong></p><p>Explanation for incorrect options:- O ption A . It is absent when the labyrinth is dead. O ption C. A false positive fistula test (i.e. positive fistula test without a fistula) is seen in congenital syphilis and about 25% of cases of Meniere’s disease (Hennebert's sign). In congenital syphilis, the stapes footplate is hypermobile, while in Meniere’s disease, it is due to the fibrous bands connecting the utricular macula to the stapes footplate. In both these conditions, movements of stapes result in stimulation of the utricular macula. Option D . A false negative fistula test is also seen when cholesteatoma covers the site of the fistula and does not allow pressure changes to be transmitted to the labyrinth.</p>\n<p>@dams_new_robot</p>", "bot": "@dams_new_robot", "video": ""}]; if (!Array.isArray(questions) || questions.length === 0) { throw new Error("Questions data is empty or invalid"); } debugLog(`Successfully parsed ${questions.length} questions`); } catch (e) { console.error("Failed to parse questions_json:", e); document.getElementById('error-message').innerHTML = "Error loading quiz data.

CPAP can stent open the collapsed segment during end-expiration. Continuous positive airway pressure (CPAP) provides a pneumatic splint to the airway and increases its calibre. The optimum airway pressure for a device to open the airway is determined during a sleep study and is usually kept at 5–20 cm H2O When CPAP is not tolerated, a BiPAP (bilevel positive airway pressure) device is used. It delivers positive pressure at two fixed levels—a higher inspiratory and a lower expiratory pressure. An auto-titrating PAP (APAP) is also available, continuously adjusting the pressure. Their disadvantages are the same as those of CPAP.</p>\n<p>@dams_new_robot</p>", "bot": "@dams_new_robot", "video": ""}, {"text": "True about vocal nodules is/are:", "options": [{"label": "A", "text": "Also known as screamer's node", "correct": false}, {"label": "B", "text": "Occur at the junction of anterior 1 /3rd and posterior 2/3rd of vocal cords", "correct": false}, {"label": "C", "text": "Most common presentation is hoarseness of voice", "correct": false}, {"label": "D", "text": "All of these are true", "correct": true}], "correct_answer": "D.
